Aero 9B nose turret from the Neptune at the National Naval Aviation Museum, Florida, 2007.Mostly the one foot longer Aero 9C turret was installed. Before the P-3 Orion arrived in the mid-1960s, the Neptune was the primary U.S. land-based anti-submarine patrol aircraft, intended to be operated as the hunter of a '"Hunter-Killer" group, with destroyers employed as killers.
The transponder gets its altitude information from an encoding altimeter mounted behind the instrument panel that communicates via the Gillham code. Gillham code is a zero-padded 12-bit binary code using a parallel nine- [ 1 ] to eleven-wire interface , [ 2 ] the Gillham interface , that is used to transmit uncorrected barometric altitude ...

[4] [3] In figure 5, several related terms and symbols are shown. Focal length (f) refers to the elevation difference between the film and the lens. [2] [4] H is the elevation difference between the lens and the sea level, which is the average level of the water surface. [2] [4] h is the elevation difference between the terrain surface and the ...
The instrument case of the altimeter is airtight and has a vent to the static port. Inside the instrument, there is a sealed aneroid barometer. As pressure in the case decreases, the internal barometer expands, which is mechanically translated into a determination of altitude. The reverse is true when descending from higher to lower altitudes. [5]
The Bendix Central Air Data Computer contains complex electromechanical mechanisms. Electrical-mechanical air data computers were developed in the early 1950s to provide a central source of airspeed, altitude, and other signals to avionic systems that needed this data.
[1] [2] It is a primary instrument for flight in instrument meteorological conditions. [3] [4] Attitude is always presented to users in the unit degrees (°). However, inner workings such as sensors, data and calculations may use a mix of degrees and radians, as scientists and engineers may prefer to work with radians.
The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
